ROG Phone 5 Battery issue

Anna-Kin

Please tell us some basic information before asking for help:
Model Name: Asus ROG Phone 5 Global
Firmware Version: Latest
Rooted or not: No
Frequency of Occurrence: Regular
APP Name & APP Version (If your issue relates to the app):
In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.
========================================
Battery mode: Dynamic
Refresh Rate: Auto
My new 3 days old ROG 5 is showing approx 6 hours of SOT with mixed usage and lasts for about 20 hours. So, I ran the AccuBattery Pro while charging the phone from 5% to 98%, and twice while charging from around 40% to 100%.
And here are the results, even after a total charge of 174%, it didn't charge to the capacity of 6000mAh.
Can anyone in the community perform the same test as well using AccuBattery Pro and see what the battery health and estimated capacity is?
For comparison I ran the same test on my almost 3 years old Oneplus 6T(2nd pic):

You should tell them that none of my business if the problem is with the phone you need to replace it as per your T&C, and if you can't refund back the money.

So if they give you back the money,you can reorder a new one.

@Reaperzwolf I did not return the phone as resetting the phone as per @thejus44's suggestion did improve the battery life.
However, I am still not sure how long the improved battery life will last as we are pretty much sure now the issue is with the software/OS and not with the phone.

@Anna-Kin that's pretty great to hear! I've heard from other people that their ROG phone 2&3 battery health sustained for plenty of time, and still sustains, actually. If the battery health goes down then I don't think it'll be a problem to go to an asus service center and ask them to replace the battery. I did disable automatic software updates, so I think it would be wise for you to do so as well, and maybe come back to the forum to see if any asus updates are making it better or worse, and then update based on that.

Compared to the 2 and 3 the split battery is to blame as well. Because the efficiency is reduced compared to a single large battery. Plus, the split batteries arent even 3000 mAh (misleading advertising), they are 2885mAh each, making the phone a 5770mAh battery phone.
I will disable auto-updates as well, that's a nice idea. I hope Asus doesn't pull off a Oneplus move and destroy the already unstable battery backup with an update.😂

@Anna-Kin haha that's true, I would definitely be wary of Asus pulling off a OnePlus. This is my first Asus phone so I'm approaching updates with some caution. Although to be honest I would do that with any device at this point.

Also while I get where you're coming from, the counter arguments I've heard is that the split batteries effectively mean that each battery discharges slower than one big normal one, and since Asus bundles only a 30W charger for the Indian market, each battery charges only at 15W, meaning that charges and discharges are slower, which is better for the battery overall. Might also reduce the point of failure, if one battery takes a dive we can't be sure the other one will as well.

So at the end of the day I guess it's best to just wait and see how it goes. It may even be the case that dual battery setup is better! The main point I'm worried about is battery replacement after 2-3 years. If that goes smoothly I'll know that Asus handled the battery side of things of the RoG phone 5 magnificently. But for now, since your issue is fixed, let us enjoy the huge battery backup right now 🙂

Alright so i formatted my phone and now see the stats. Its pretty amazing now. This is how it should be. So my guess is that every time a new update come. Flash it manually and do a format🤣
